Copying text with footnotes

I am new to the forum, so I do not know, whether I should post under “Feature requests” or under “Plugin ideas”. I am happy for any suggestions or workarounds you know.

Use case or problem

I started using Obisidian as my main text editor for academic work. One huge problem I have with Obsidian, though, is copying and pasting parts of notes with footnotes. I am using tidy-footnotes and better footnote as plugins, which work wonderful, but – to my knowledge – do not offer any support for my problem.

Example:
Note 1:
This is the text I want to copy.[^1]
[^1]: This is the footnote I want to copy.

Note 2:
This is the text I want to insert the other text in.[^1]
[^1]: This is the already existing footnote with the same number.

Result so far, after copying note 1 in note 2 and also manually copying the footnotes:
Note 2:
This is the text I want to copy.[^1]
This is the text I want to insert the other text in.[^1]
[^1]: This is the footnote I want to copy.
[^1]: This is the already existing footnote with the same number.

Tidy footnotes leads to the following:

This is the text I want to copy.[^1]
This is the text I want to insert the other text in.[^1]
[^1]: This is the already existing footnote with the same number.

Result I want to get:
Note 2:
This is the text I want to copy.[^1]
This is the text I want to insert the other text in.[^2]
[^1]: This is the footnote I want to copy.
[^2]: This is the already existing footnote with the same number.

Comment: I do not want to merge notes, but only copy parts of notes with footnotes to another note and then rename/order the footnotes in the new note.

My problem was already asked in a shorter way in Extract this heading to include footnotes and Dealing with copy-pasting footnotes, without getting an answer.

Proposed solution

I do not have the perfect solution, but one idea: If I had a plugin, that could rename my footnotes in the note, I want to copy, (Note 1) then I could start the numbering at a very high number (e.g. 100). I then could copy the note and the footnotes manually and renumber with tidy footnotes. That might solve the problem.

Example:

Note 1:
This is the text I want to copy.[^1]
[^1]: This is the footnote I want to copy.

Renumbering footnotes in Note 1 through renumbering, starting with e.g. 100:
Note 1:
This is the text I want to copy.[^100]
[^100]: This is the footnote I want to copy.

Note 2:
This is the text I want to insert the other text in.[^1]
[^1]: This is the already existing footnote with the same number.

Result after copying manually:
Note 2:
This is the text I want to copy.[^100]
This is the text I want to insert the other text in.[^1]
[^100]: This is the footnote I want to copy.
[^1]: This is the already existing footnote with the same number.

Tidy footnotes then renders the wished result:

Note 2:
This is the text I want to copy.[^1]
This is the text I want to insert the other text in.[^2]
[^1]: This is the footnote I want to copy.
[^2]: This is the already existing footnote with the same number.

Current workaround

Until know, I am forced to renumber all the footnotes manually, which in academic work with 50+ footnotes per note is very tiresome and letting me think, that I will have to switch to LaTeX for text editing. If you know other workarounds, I would be really happy.

Both did not get any answers.

Any help, ideas etc. will be highly appreciated.
